Looming changes to safety laws have spurred a Wairarapa school to ban pupils from climbing trees.
The Health and Safety at Work Act comes into force early next month in response to the Pike River Mine disaster, with the initial aim of ensuring big business is vigilant about worker safety.
The act will also cover community agencies and charity events, and effectively makes principals liable for fines of up to $600,000.
Greytown Primary School principal Kevin Mackay last week sent out a newsletter saying pupils were temporarily banned from climbing trees "until there is certainty" regarding the new act.
There were about half a dozen trees pupils climbed and he refused to paint height limits, though taller trees were always out of bounds.
